AUTOMATIC REPLAY AND RECORD SHIFT FOR rHo oGRaPfis.

Application filed May 7, 1920. Serial No. 379,527.

T 0 all whom it'mag concerns Be it known that I, EDGARE. Bnosn's; a citizen of the United States,'residing at Pittsburgh. Allegheny County. Pennsylvania have invented a new and useful Imhit'ts for'Phonographs. of which the following is a full. clear, and exact description.

The presentinvention relates broadly to phonographs. and more particularly to the type employing disk records. v

The principal object of thepresent invention is to provide means adapted to l e attached to phonographs of standard construca tion enabling a single record to be replayed any desired number of times, or permitting the automatic shift-ing, of 'recordsafter a single playing thereof. v

- I A further object oftheipresent invention .is to provide an automatic replay for phonographs comprising .mechanic'ajl means for lifting the sound box from the record, transferring the-same. to the starting position and then gradually lowering the sound box into engagement with the record. I A still further object of the present invention is to provide electrically operated means for controlling the lowering of the sound boX'onto the record. the electrically. operated means being energized'at desired, "intervals which may be -timed topermit the change of records or to automatically replay the samerecord as soon as the sound .box is in position.

Another object of the present invention is to provide. a mechanically driven record.

shifting arm.'the'rotation of which-is controlled by means of a friction clutch electrically operated at predetermined times.

Still another object of the present inventionis to provide a phonograph with two additional tables. one serving as a source of supply for unplayecl records, and the other servnig as a source of storage for played records, with means for automatically shitting the records as required; the shifting means being electrically controlled and mechanically operated for synchronizing the shifting of therecords with the operation of the phonograph."

An additional object of the present invention is to provide means for readily changing the device from an-automatic replay for an individual recordto an automatic playing and record shifting device.

The foregoing and otherobjects, together with their attendantadv-antages will be apthereof. it being premised that changes may be made in the various details and the manner of operation. within the scope of the appended claims, without departing from the spirit of the'invention. c

"In my Patent No. 1266.76? of May 21, 1918, there is disclosed mechanism for automatically shifting records for phonographs.

The present invention relates broadly to improvementson the construction disclosed in this patent and combines therewith a replay which iscontrolled by electric replay magnets the circuit of which may be controlled to vary the operation of the device.

Referring more particularly to Figure 1 of the drawings, there is illustrated a portion 1 of the body of the support for. the phonograph which may be of the cabinet or other w'el -known type carrying the usual record These features may be of any usual well known construction and constitute no part-of the present. invention except as they co-operate with the mechanism provided for automatically replaying or shifting records. Secured to one'c'orner of the support 1 is *a'bracket comprising an arm 4 carrying a table 5 for the reception of played records, and asec- 0nd bracket 6 carrying a table 7 upon which may be placed aseries of unplayed records. Extending'vertically through the center of the attachment is a shaft, referred to in de-j tail hereinafter, carrying a record shifting arm 8 adapted to be driven by the shaft and provided on its outer end with means for ena ing a record and carrying it, after it. has

been played, from the, record table2 to the table 5 where it is automatically dropped.

. The arm 8 then continues its travel in the direction of the arrow A to the table 7. where 1t picks up an unplayed record from the supply thereon provided and carries the same to the record table 2. It will be apparent that the usual tempo control and brake control for the. recordtahle may be provided, as

indicated. in the drawings.

' Replay device-It is necessary. in order to replay records, to providemeans for shitting the sound box and stylus automatically from the inner sound groove of the record to the outer orstarting groove. and this mechanism, in the present instance, has been termed a'freplay device- The mechanism is illustrated as an attachment forstandard machines; more particularly in Figures 2 and 3 as comprising a cam 9 secured to the mandrel 10 provided for driving the record table 2. This cam extends around the major portion of the mandrel and is provided with a surface a. gradually inclined to constitute a lifting device; a surface-b sharply inclined to permit arapid descent of the sound bo'x toward the record, anda third surface 0 graduall inclined so that during the last portion of the travel of the sound box it will be lowered without jar into engagement with the record. Between the ends of the surfaces a and 0 there is provided an opening 11 through which one end of the arm for accomplishing the transfer of the sound box is adapted to pass. This arm is generally U- shaped and comprises a leg 1.2 journaled adjacent its opposite ends in a bracket 13 which is adapted to besecured to the support 1 below the record table and extend radially outward from the mandrel 10. end of the leg 12 is bent downwardly in. the form of a cranlcld; which crank is in turn The inner provided with a pin or roller 15 adapted to engage. at desired intervals, the cam 9. Normally. the pin or roller 15 lies below the body of the cam, as clearly indicated in Figure 3 of the'drawings-g The other leg 16 is provided with asliding sleeve 17 carrying at one end an adjustable stop 19 adapted to be engaged by a suitable projection 20 formed. on the sound box 20', this engagement occurring when the stylus has finished playing the record. The sleeve-17 is also provided with a second stop 22 adapted to engage the sound box 20in aposition where it mav be vertically lowered into engagement with the outer groom of asound record. It will be apparent that this stop may also be adjustable to permit the device to be used with standard records of diiferent dimensions.

20 is illustrated as in engagement with the stop-22. f

The leg 1.6 is normallyheld-in the full line position illustrated in l ignres 1 ,2 and 3,

and is moved from this position to eflect transfer of the sound box when theprojection 20 engages the stop 19. through mechanism now to be described in .detail.

Referring particularly to Figures 6. 7 and 11. it will be noted that the legs 12 and 16, which legs are.connected by the yoke 23,

extend through mechanism controlled by reing 26 for the leg 12., 'Pivotally secured to the bearing 26 is a holding lever 27 extend-- play magnets 24. These replay magnets are L mounted in a frame 25 WlllCh carries a bearing forwardly. toward the magnets 24 and having its free end engaged by a catch 28 having a pivotal mounting 2-9 on the frame ,25 and normally held in engagement with the holding lever 27 by a spring 30, the ex jection 34: on the sleeve 17 on the leg 16.-

When the projection 20 engages the stop 19. the continued'travel of the. stylus in the record groove will slide the sleeve 17 inwardly, thereby causing the projection 34 to engage the projection 36 and draw the catch 28. against the action of the spring 30-,,out of engagement with the holding lever 27.

The spring 32 will now be free to lift theholding lever 27 which will in turn lift the leg 16 which overlies thesame. This movement will be enough to cause the pin or roller 15 to pass vertically through theslot 11 in" the cam 9 whereuponrotati-on of the. mandrel 10 will cause the same to be engaged by the cam 9. During the travel of the pin 15 over the cam surface tithe-leg 16' will be moved from its full lineposition shown in Figures 1, 2, 3 and 6 to the dotted line position shown inthese figures, thereby engaging the sound box and lifting the same from engagement with the record. The inclinatio'n of the leg 16 will be suffieienh'as clearly illustrated, to cause the sound box to slide by gravity along the sleeve 17 into engagement with the stop 22. Engagement with the stop will check the movement of the sound box and at the same'time slide the sleeve 17 inwardly. so that upon descent of the leg 16 the projection 34 will be in the proper position. to pass behind the angular projection 33. During the travel of the pin tion of the replay'device, the leg 16 is 'proa or roller 15 on the cam surface'b the weight" 3i and lift the, same out of engagement with of the sound box will be sufiicient to cause a comparatively rapid descent or lowering of the legil6. When the pinor roller lo en gages the surface 0. the rapidityof the lowering .movement will be checked. and when the pin 15 finally leaves the cam surface c. the stylus will have been gently lowered into'engagement with the record.

-For resetting the parts after each operavided with a pivoted lever 35. which, in traveling from its full line position shown in Figure 6 to the dotted line position shown therein will force the,lever'2T-downwardly against the action of the leaf spring 32 so that the catch 28 may engage the same automatically andholdit in its'original position. The nose 36 of the catch '28 is -inclined, as

.holds the arm'16in the clearly shown in Figure 7, to permit the resetting of the holding lever 27, as will bev apparent.

The foregoing operations will occur with the mechanism describedupon the completion of the playing of each record, as long as the phonograph is in operation, unless some means is provided for holding the 1e 16 and the sound box 20 in their elevate positions with the stylus out of engagement with the record. In the present case I have provided mechanism for holding the parts in this inoperative position, nism will now be described.

Pivotally carried by the leg 16 is a lever 37 normally extending forwardly, between the replay magnets 2-1 and supported on the cross bar 38 to be described in'detail hereinafter. This lever is provided on its lower surface intermediate the ends thereof with a detent- 39 adapted. when the lever is in the dotted "line position shown-in Figure 6, to engage and hook over the cross bar 38.

and this mecha- .This lever automatically drops into this position as the arm 16 is raised, and thereby elevated position until released.

In the. present case, I have provided electrically controlled means for disengaging the lever 37 from the cross bar 38 to permit loweringof the sound box. This means comprises the replay magnets 24 which are formed with hollow cores adapted to receive the core members or. armatures 40 carried by the transversely extending bar 41. .The bar 41 carries an upstanding lug 42 which. in the normal position of the parts of the "replay device during playing of a record. underlies the free end of the lever 37 out of engagement therewith. lVhen the parts are in their elevated. inoperative, positi0n, the free end of the lever 37 immediately overlies the lug 42 so that when the circuit of th'ereplay'magnets 24: is energized to lift the core pieces "or. armatures 40 and the transverse bar 41 connecting the same. the lug 42 will engage the underside of the lever the cross bar 38'. thereby permitting the parts-9to gravitate to their operative positions. During the period that the parts are in' their inoperative elevated positions, the pin or roller 15 occupies such a position relative to the highestportion of the cam 9- that' it is engaged thereby during each revolution of-the table mandrel. This results in a movement of the leg 16 from the dot and dash center lined to the dot and v 1 \Yhen the. device is used merely for re playingrecords, it is desirable that .means i be provided for preventing the engagement .of the detent 39 with the transverse bar 38. For this purpose I mount a second trans verse bar 38 on a lever 43 having a pivotal mounting 44 on the frame 25.. When the lever' 43 is in its full line position shown in I changed by shifting the position of the leyer 43.

In actual practice, it has been found desirable to provide the frame with a leaf spring 45 which may be conveniently mounted onthe bearing 26 so as to engage a stop 45? on the lever 37 as the lever rises from its lower to its upper position under the influence of the leg 16. Due to the provision of this spring, when the detent -9 is disengaged from the bar 38, the spring will assist the ble.

gravity action and insure the lowering of the sound box. The foregoing replay device,'as described and illustrated, is operative by itself with the mechanism described. It has been found, however, that the replay is particularly adapted for use in connection with an automatic record shift due to the provision of means for holding the sound box in-its elevated position for predetermined periods of time. The construction and operation of the automatic record shift with relation to the replay device will now be described.

Automatic record shift.-Broadly,, the recordshifting device comprises an arm adapted to be operated automatically at predetermined times to pick up a record from the record table after it has been "played, transfer the same to a desired point, pick up a new record, and place it on the record table in place of the record previously [removed therefrom. This'arm 8, before described, is provided with a hub portion 46 carrying an adjustable bearing 47 c'o-operating with the upper end of a shaft 48. The hub 46 is held in central position about the shaft by means of a. lower orintermediate bearing 49, clearly illustrated in Figure 13. For rotating the shaft 48 it may be extended through the support 1, in a suitable bearing 50 and provided on its lower end with anydesired type of gearing 51 adapted to be driven from the mandrel 10 through a transverse shaft 52 and gearing It will be apparent from the nature of the gearing provided that the shaft 48 is rotated continuously during the rotation of the record ta- The arm 8 is not adapted, however, during the entire operation of the record table to swing continuousl and for this reason there is provided a clutch enabling a driving connection to be established at will between the shaft 48 and the hub 46. As I illustrated, this connection may comprise a solenoid '54 carried by the hub 46, and .provided with a core 55 having its inner end roughened or serrated to engage a similar surfacev 56 on the shaft 48. \Vhen the solenoid 54 is energized to draw the core 55 to its inner position. the parts will be frictionally clutched together and driven in unison, but upon deenergization of the solenoid this driving connection will be destroyed.

For controlling the circuit of the solenoid, the hub 46 may be provided with a plurality of slip rings, illustrated as four in number,

and bearing the reference characters 57 to.

60, inclusive. These slip rings constitute a portion of an electric circuit, illustrated for sake of clearness diagrammatically in Figures 16 to 20. v

Referring particularly to Figure 16, there are illustrated two line wires 61 and 62, respectively. The line'wire 62 leads from any desired source of current through a safety fuse 63 to a brush 64 in engagement with the 1 periphery of the'slip ring 60. This ring has an electrical connection 65 with the slip ring 57 which, in turn, has an electrical connection 66 with the frame 67 of a make and break devicemounted on the arm 8.' This make and break device, as clearly illustrated in Figures 14 and 15, comprises a movable member 69 pivotally connected to the frame 67 and carrying a contact 70 adapted to cooperate when the make and break device is in closed position, with a second contact 71 insulated from the frame 67. This contact 71 has a connection 72 with the solenoid 54,

nccted through a wire 73 with the ring 58. Clo-operating with the ring58 is "a brush 74 having a connection 75 with the binding post 76 on the frame of the replay magnets 24. From the binding post 76 the current passes through the frame 25 to the connecting bar 41 for the solenoid core pieces 40, thence to the opposite side of the frame 25 to the binding post 77. This portion of the frame 25 is insulated by means of hard rubber fibre or the like 78. from the remainder of the frame so that the circuit can only be completed through the bar 41 when in 1ts lower position in engagement with the frame portions described. The terminal '77 has a.

connection 7 8 with one side of a switch contact 79, the opposite contact 80 of which has aconnection 81, with one contact 82 of a manual switch controlled by the lever 43 of the replay device. From the contact 82 the current is adapted to pass when the switch is closed through the switch blade 83 to the wire 61. From the foregoing it will be apparent that when the contacts 79 and 80 are bridged and the switch blade 83 is in its closed position in engagement with the contact 82, current will flow from the line and the opposite side of the solenoid is conwires 61 and 62 through the solenoid 54 for energizing the same and forcing the armature into engagement with the shaft 18 "causing rotation of the arm 8. Normally,

however. the contacts 79 and 80 are not connected by a switch, this condition being shown in Figure 16, so that the arm 8 duringthe playing of a record is permitted to extend over the record table, as shown in Figures 12 and 13.

Upon completing the playing of a record, the elevation of the leg 16 is adapted to connect the contacts 79 and 80 by means of a suitable switch mounted in the frame 25 of the replay device. Referring again particularly to Figure 6. the lever 37 is illustrated as provided with pins 84; extending beyond the opposite sides thereof. During the time that the lever 37 moves from its full line position illustrated in this figure to its dotted line position, these pins'will drop over and straddle the tail S5 of the switch blade 86 pivotally mounted at 87 to the Continued for moving the switch 86 from its full line position to its dotted line position, thereby closing the circuit through the contacts 79 and 80 and energizing the solenoid 54 in the manner described.

During the movement of the leg 16 from its lower to its upper positions, a pinor pro jection 88 on the yoke 23 engages a pivoted .member 89 secured to the arm 90 and draws the same to the left, as viewed in Figure 10, against the action of a spring 91. This operation forces a plunger 92 inwardly with in a dash pot cylinder 93, movement in this direction being permitted by the opening of a flap valve 94 in the base of the plunger 92.

The arm 90 carries a pivoted contact blade 95 adapted normally to engage the contacts 96 and 97, as shown in Figure 10. Once this circuit is broken, however. the time element, comprising the dash pot mechanism described. will prevent immediate closing of the circuit.

This circuit, referring again to Figure 16. may-be traced from th line wire 62 to the contact 70, as before described, and thence to the contact 71 and through the wire 98 to the disk 59. This disk is provided with a projection 99 adapted to engage a wiper or brush contact 100 having a connection 101 with the contact 96 from which the'current flows through the blade 95 to the contact 97 and wire 102 to one of the replay magnets 24. These magnets are connected in series. as shown, and the opposite terminal of the other replay magnet is connected to the contact 79. When the switch 83 is closed. as before described, current will flow to the line wire 61. From the foregoing. it will be apparent that if the circuit, including the replay magnets 24, were energized at the same solenoid.

through the lug 4:2, to lower the leg 16,

thereby dropping the sound box before shifting of the records occurs. The provision of the time element prevents this operation, however. by opening the circuit between the contacts 96 and 97 for a sufficient period of time to permit the projection 99 to pass out of contact with the brush 100 due to the rotation of the arm 8. hen the time element resumes its original position. the circuit between 99 and 100 will be broken and the replay magnets will not thereafter be energized until a complete revolution of the arm 8 has occured and the contacts 99 and 100 again brought together. This complete revolution will be sufficient to remove the played record and supply an unplayed record, after which time itwill be desirable to lower the sound box.

The diagram in Figure 16 illustrates the circuit connections during the playing of a record.

The diagram in Figure 17 illustrates the circuit connections as they are at the time arecord has been played and the arm 16 is in its elevated position. the time element in this. diagram being illustrated as in its open position. as shown in elevation in Figure v Carried by the outer end of the arm 8 is a fixed solenoid .103 provided With acore 101 fixed to the arm 8 and extending longitudinally through the open center of the Co-operating with the solenoid 103 is a second'solenoid 105 connected in parallel to the first solenoid and provided with a projecting core 106 adapted to slide vertically around the core 104vand into the open space of the first solenoid. when the solenoids are energized. The lower portion of the core 106 of the solenoid 105 is formed with a pocket .107 adapted to lie [over the projecting end of the mandrel 10 during the playing of av record. For preventing rotation of the solenoid 105fthe arm 8 is pro vided with a finger 108 to the lower end of which is secured a guide rod or wire 109 connected at its outer end at any desired point to the solenoid. After the record on the record table has been played. as described. and at the same time that the solenoid 54 has been energized for establishing a driving connection between the shaft 18 and the arm 8. the solcnoids'103 and 105 are enerized to lift the played record from the table.

wire 110 to the solenoids 103 and 105, re-- spectively, the opposite sides of the sole noids being connected. by the wire 111. to the ring 58. From the ring 58 thecircuit is com- .pleted through the replay device, as before described. I

It will thus be apparent that the arm 8 starts to rotate in the direction of the arrow A, it will lift the record from the record table and carry the same as long as the solenoids 103 and 105 are energized. For breaking the circuit to these solenoids, and at the I same time breaking the circuit'throughthe solenoid 54, there is provided a support 112 partially surrounding the hub 46and provided with an adjustable stop 113, clearly shown in Figure 14. As thejarm 8 rotates to its position above the table 5, the pawl 114 pivotally mounted on the free end o't'the bell crank lever 115 which is, in turn. provided with a pivotal bearing 116 on the hub 46, will engage the stop 113 and-swingthe bell crank lever against the action of the spring 117' into dotted line position shown in Figure 15. This will, in turn, swing the lever '118 about its pivot 119 to the dotted line position shown. in this figure,'the pivoted end 1200f the lever during this period of its travel passing freely over the projecting end of the pivoted portion 69 of the make and break. device. As soon as the pawl 114 passes out of engagement with the stop 118, the parts will move to their original position. During this movement, however. the pivoted end 120 of the lever 118 will engagethe free end of the member (39 and separate'the contacts 70 and '71, thereby breaking the circuit to the solenoids'54, 108

and 105, simultaneously, causing the record to be dropped, and breaking the driving connection between the shaft48 and the arm 8. As soon as the record is dropped, the momentum of the arm 8 will carry it away from the record so that when the circuits are re XI established the recordwillnot be again htted from the table 5 for the played records.

It will be apparent that by making the-stop 113 adjust-able, the exact point of dropping the played record maybe controlled, Connectedto the members (37 and (39 of the cii-" cuit making and breaking device is a cylinder 121 and a plunger 122, respectively, constituting a second time element correspond- 'ing to the time element before dcs:rihe l.

This time element'is provided to hold the contacts 70, and 71 separated a su'liicient time to permit the momentum of the arm 8 to carry the lifting solenoids for the record out of engagement with the record, as described. Thistime element is only opcra-..

tive ,forholding the-contacts sepai'ated'a comparatively short time, and during the travel of the arm from the table 5 to the table 7, the circuits will be re-established. Just prior, however, to the time that the arm reaches the storage table 7 for the new reeords, the pawl 114 will engage a second stop. i

123 similarto the stop 133, and the operation just described will be repeated, permitting the solenoid 105 to drop into engagement with the new record over the centering pin 124 which insures the correct positioning of the record. The time element for the circuit make and break device will again permit closing'ot' the circuits and the new record will be lifted from the table 7 and carried to the record table 2. Just prior to the timethat the arm reaches the center or the recordtable 2 thepawl 114 will again engage an adjustable stop 123 causing the record to be dropped onto the table and the solenoid 105 to be centered over the upper portion of the niandrel'lO, as shown in Figure 13. At thistime, the contact 99 will engageftlie brush 100, thereby'closing the circuit to the replay magnets 24, energizing the same and causing them to raise the lug 42 to release the lever 37 andlower the souiid box onto the new record. I I

In Figure 18 the circuit connections are shown as. they are at the time the played record is droppedonto the table 5, the contacts and 71 being shown as separated.

In Figureg19 the circuit connections are shown as they are at the time the arm reaches the table 7 for the new records, the contacts 70 and; 71 also being open in this ligure to permitthe solenoid 105 to drop into engagement with a new. record; and the contact 99 illustrated as having traveled "substantially two-thirds of a rotation, this amount depending upon the. exact positioning of the tables 5 and 7, as will be apparent. In Figure 20 the circuit connections areillustrated as they are at the time the arm drops the new record onto the record table,

the contacts 99 and 100 being shown in engagement, and the next change in the circuits will take place upon the lowering of the leg 10 resulting in moving the switch S6 frombetw een the contaits 79 and 80,

utilizedthrough the cam 9 for raising the sound box, thereby obviating the necessityv of employing separate lifting means for this purpose. ()nce having been raised from the record, the lowering of the sound box is controlled by the electrical means described. The switch 83-bcmg operated bythe lever 43, it will be apparent that when the lever 43 is moved from one position to the other to change the device from an automatic replaying device to a combined replaying and record-shifting device, the switch 83 will be automatically thrown to the proper position. and vice versa.

In Figures 21 to 26. both inclusive, there is illustrated a slightly modified arrangement which. in some instances,'may be desirable in place of the mechanism just described. due to the elimination of the time elements of the character shown. In these figures parts corresponding to the parts already described are indicated by the same reference characters with the letter a afiixed thereto. In Figure 21, the arm 8 is indi-.

cated as provided at itsouter end with the solenoids 103 and 105. these solenoids in this form of my device being prevented from rotational movement by a guide rod 125 secured at its lower endto the spool for the solenoid 105 and having its intermediate portion passing through the spool flanges for both of the solenoids.

The upper end of the guide rod 125 is struction. when the solenoid 105" moves to its lower position, the guide. rod 125 will be pulled downwardly, thereby elevating the core 129 for the hereinafter.

Extending longitudinally through the.

core 129 is a rod 132 having its lower end in engagement with one end of-the bell crank lever 133 pivotally mounted'at 134 in a slotted portion of the core 129, and having its opposite end projecting downwardly below the end of the core. Vhen the arnrS, carrying 'a new record from the supply table 7. reaches the position over the mandrel 10 for the record table 2 the lower portion of the pawl- 133 will engage the upper end of-the mandrel and lift the rod 132. The upper end of this rod 132 underlies a spring contact 135 secured at one end to the support 137 on the core 129 and adapted to be pushed upwardly by the rod 132 into engagement with the contacts 136 for establishing electrical connection between these contacts. The hub portion 46 1 of the arm 8 surrounds the shaft 48; in a manner similar to that already described in connection with the preceding form of my invention. and carries-two rings 138 and 139 respectively, taking the place-0f I the the purpose to be described tiv-"ely, "thereby causing be dropped on a record table in playing four slip rings 57 to 60. The side of the hub 46 also carries a solenoid 54 provided with a core 55 adapted to form a driving connection between the shaft 48 and the arm' 8. In this form of my invention, the upper end of theshaft 48 has an extension 140 carrying a roller 141 in engagement with the core 142 of the solenoid 143. The

opposite end of the core 142 is provided with a contact or switch member 144 adapted to ,co-operate with the two contacts 145. The free end of the core 142 projecting beyond the roller 141 is formed with a hook 146 adapted to engage the upper end of a lever 14? having a pivotal mounting 148 on the hub 46 of the'record shifting arm. The lower end of the lever 147 carries a circuit making or switch member 149 adapted to co-operate with the fixed contacts 150 secured'to and projecting upwardly from the support or cabinet 1 Vith this mechanism. and referring more particularly to Figure 26. the operation-wlll be as follows. as'sumingthe switch 83 to be in its closed position.

The rod 132 having been raised to close the the contacts 137. current will flow,through line wire 62 and safety fuse 63 to the 139. From this ring the current will flow through the wire 153 to the contacts 137 :and 'thence through the wire 154 to the solenoid 143 thereby energizing the same and causing the core 142 to be moved to the left. as viewed in Figures 21'and 22, against the action of the friction roller 141.

tween the contacts 145. From the solenoid 143 the current will flow through the wire '1 155 'to'the ring 138 and thence through the brush 156 and wire 157 to the contact 79.

From this contact the current will flow through the switch member 86 of the replay device to the cont-a'ct- 80 and thence .through the wire 158 and'switch 83 to line wire 61". Opening-the contacts 145 willfbreak' the circuit through the solenoids 54. 103 and1 105, respecwire 151 in electrical connection with brush 152 co-operating with the ring This will break the electrical connection be position The dropping of the solenoid '105 will. however, result in lifting the core 129, v

as before pointed out, thereby enabling the pawl 133 to pass from its dotted'line posi tion shown in Figure 25 to the full lineposition shown in this figure. which will re sult in again. lowering the rod 129 and opening the electrical connection between will now be effective for slowly advancing the core 142'to its original position to es-' tablish electrical connection between the contacts 145. During this travel the hook 146 thereon will'engage the lever 147 and the contacts 137..

Current will" now flow from the line wire 62 through the safety fuse 63 and wire 160 to one of the contacts 150; thence through the member 149 to the other contact which is connected by wire 161 to one side of one of the replay replay magnet is connected by wire 162 to wire 158 through whichi'the current flows to the line wire 61 through the switch 83 The replay magnets being energized, the sound box will be lowered into engagement with the record through the mechanism already described in detail in connection with the other figures of the drawings. I

' Uponcompleting the playing of the record, the sound box lifting leg 16 will lift the sound box from the record and throughthe mechanism provided will draw the switch 86 between the contacts 79 and 80 described heretofore. "completed, the played record will be lifted from the recordtable and transferred, and

In this position-current will flow from the line wire 62 to the ring 139 and fromzthis ring through wire 163 to one side of each of'the solenoids 103 and 105. After traw ersing the solenoids the current .will flow through Wire 164 to one of the contacts 145 and thence through the member'144 to the other contact 145. The current will flow from the lastmentioned contact 145 through the wire 166 to the solenoid 54;, the opposite side of which is connected by wire 167,

to the ring 13S.v From this ring the circuit will be completed to the line wire 61, as These circuits being the regular sequence f operations will take place resulting in the positioning of a new record onthe record table.

The advantagesof the present inventionreside in the. provision of .means controlled by the drivingjmechanism for the phonograph for positively lifting the sound box out of engagement with the record, and in the means for controlling the subsequentlowering 'of. the sound box. i

Further advantages result from the means provided for conveniently changing the demice from a replaying device to a combined replayingjand record shifting device.
